UNITED STATES JOSEPH PEYSER, OF MOUNT VERNON, NEW YORK.

Application filed. ()ctober 29, 1921.

To all whom it may concern:

Be it known that I, JosErH Pnrsnn, a citi- Zen of the United States, anda resident of Mount Vernon. in the county of Nestchester and State ofNew York, have invented certain new and useful Improvements in Seanr ingTools, of which the following is a specification.

The present invention relates generally to seaming mechanism and has forits main object and purpose the provision of means whereby more timewill be given in which to perform the in and out movement of the seamingtools.

In devices of this character it is, under certain conditions, desirableto use two first operation seaming tools and two second operationseaming tools. To avoid undue crowding of the parts I employ twoseparate concentric seamer cams, one for actuating both of the firstoperation seaming tools and the other for actuating both of the secondoperation seaming tools.

The invention may be embodied in a construction in which the containerto be seamed rotates and the seaming tools are relatively stationary,or, as in the present case, the container may be stationary and theseaming tools may revolve around the work. In either event, the twoseamer cams have an effective circumferential displacement of onerevolution with respect to the seamer head, which condition may beobtained either by having the seamer head stationary and the cams makingone revolution to each seaming cycle, or by rotating both the seamerhead and cams, say, in the proportion of fifteen to sixteen revolutionsto each cycle of the machine.

In the accompanying drawings, the invention is disclosed in a concreteand preferred form in which Fig. 1 is a vertical sectional view on theplane of irregular line 11 of Fig. 2 through a seamer head embodying theinven tion.

Fig. 2 is a top plan. view of the parts shown in Fig. 1 partly insection.

Fig. 3 is a vertical sectional view on the plane of line 38 of Fig. 1.

1 indicates a chuck which is the complement of the usual pedestal (notshown) and which in this case is non-rotating. 2 is the seamer headrotated by means of suitable Serial No. 51 1,343.

gearing (not shown) and carrying first and second operation seamingtools 3 and 4.

Two concentric annular cams 5 and 6 are '9 and 10, the members ofeachset being diametrically opposed to each other, and the members ofthe two sets being at right angles to each other. Each of said guidescontains a slide 11 which carries a seaming tool. Each of the slidescarries a cam roller, two of the cam rollers 12 engaging with firstoperation seaming cam 5 and the other two cam rollers 13 engaging withthe second operation seamer cam 6.

During rotation of the parts the two 0ppositely disposed first operationseaming tools 3 will first move inwardly and seam the work, the secondoperation seaming tools 4 being in their outermost position; andthereafter the two second operation seaming tools 4 move inwardly tocomplete the seaming operation while the first operation seaming toolsmove outwardly. During the period when the cams move the tools intoneutral position the container is removed from engagement with the chuckand another container placed in position. The parts 14 of the secondoperation seamer cam which are adjacent to the active portions of thecam are rendered elastic by cutting away a portion of the metal as shownto permit the second operation rollers to pass over the extra thicknessof metal at the longitudinal seam of the body of the container. Anysuitable means may be used to adjust the position of the seaming toolsto permit the machine to be employed to seam different sizes ofcontainers. In the present instance each seaming tool is carried by aneccentric member 15 seated in an opening 16 in slide 11, and by turningthis eccentric member the seaming tool can be adjusted. The means forefiecting turning movement of the eccentric member consists of a sleeve17 connected with the eccentric member by means of pin gether. Spindle21 of the cam roller is carried by a plate 22 removably seated in recess23 of the slide.

I claim:

1. seaming mechanism comprising: a seamer head, two diametricallyopposed first-operation seaming tools slidingly mounted on said seamerhead, two diametrically opposed second-operation seaming tools alsoslidingly mounted in the seamer head but at right angles to thefirst-operation seaming tools, two concentrically disposed seaming camsdisposed within the seamer head, separate connections from the twofirst-operation seaming tools to one of said cams to operate saidfirst-operation seaming tools in unison, and separate connections fromthe two second-operation seaming tools to the other of said cams tooperate the second-operation seaming tools in unison.

2. seaming mechanism comprising: a

chuck, a seamer head, two first-operation seaming tools, twosecond-operation seaming tools, two concentrically disposed seaming camsarranged in the same plane, means for actuating the first-operationseaming tools from one of said cams and means for actuating thesecond-operation seaming tools from the other of said cams.

3. Seaming mechanism comprising: a chuck, a seamer head, a plurality ofseaming tools, two concentrically disposed seaming cams arranged in thesame plane, means for actuating one of said seaming tools from one ofsaid cams, and means for actuating another seaming tool from the otherof said cams.

Signed at New York city, in the county of New York and State of NewYork, this 27th day of October 1921.

JOSEPH PEYSER.
